Need help picking a PSU
Edit: thanks all for your input, I've taken all the input and tried to find a better proces 850W PSU, but given the current discount on the 1000W be quiet! there is just nothing else beating that deal, so I've gone with that.
My current setup is an i5-12400F + RTX 3060 Ti, 2x8GB 2666 MHz, 2x 2TB 3,5" HDD, 1x 1TB NVMe, 3 case fans, 1 air cooler, 0 RGB.
All PSU calculators tell me 650W is just enough and 750W is a comfortable headroom.
Right now I have an aging Seasonic S12 II 620W PSU that causes no issues as far as powering the system goes, I've had absolutely no problems with it whatsoever in the 5 years I've had it (started on an older, much less power hungry configuration). Except one thing. I'm pushing it close to its limits and the fan is going, it's LOUD. I can't stand hearing it over the gameplay.
So I've decided to upgrade and get something that will be suitable for my inevitable cpu+gpu upgrade a few years down the road.
My choices come down to two PSUs:
- be quiet! Pure Power 12 M 1000W 80 Plus Gold ATX 3.0
- Corsair RM850x 850W 80 Plus Gold
There's a sale right now and they are priced almost the same at around 135€. The sale does not apply to an 850W variant of the Pure Power 12 M, making it and the 1000W the same price at this moment.
At first glance it looks like I should go for the 1000W be quiet, more headroom for the same price, but idk, Corsair might be more.. reliable? Both have 10 year warranties. Both are overpowered for what my components require, and that's exactly the point. I want this shit to be silent even if I'm pushing it.
Is there a better choice I should consider? Also, if the price on sale isn't as attractive as you'd expect, we get crap deals all around in my country so that's that.
You're viewing a single thread.
I'm using a 650W PSU from be quiet (the straight power series) and I'm using more power consuming compoments than you are (R7 3800X + 3070) and I don't hear my PSU. I know you said you want to overspec but honestly save yourself the money, get a good be quiet one and that's it
If you're underusing your PSU, that's also not good since its efficiency will be worse. But if that's no concern for you then feel free to go for the overspec
Thanks for pointing out underusing the PSU. I actually went ahead and checked clearesult's test report, and assuming I'd be pulling 200W most of the time (pulling this out of my ass), efficiency for that load is 91.05%. Pulling 500W in a long, demanding gaming session with this PSU means efficiency of 91.2%, a negligible difference.
A 650W variant costs 111€. 750W is 125€. 850W is 135€, the same as 1000W with current discount.
I'd be happy to go for a cheaper 850W PSU, but this is kinda the best deal right now for me.
To be clear. I'm not hell-bent on that 1000W PSU. I'm happy with a different option, but price to wattage ratio leans me to that choice.
